So that guy is commenting from Europe? And there are no (invented in Europe) saxophones?

I wonder if he had ever heard Arthur Pryor. That's a more severe vibrato than anything you'll hear on a "jazz" recording of that era.

I'm always skeptical of any use of the word "jazz" that early because they seemed to apply it almost any dance music that was odd in some way. They might talk about having heard some "jazz" but it's hard to know what they encountered.
